If your Aurora home smells like dog or cat urine, store products and regular carpet cleaning won't fix it — the urine crystals are trapped deep in the pad and subfloor. We eliminate them completely. Not mask. Not reduce. Gone. Serving Aurora pet owners since 1981.

Aurora is the largest city in our service area and the most architecturally split. Drive from the Near Eastside Historical District out to Far East Aurora and you cross 100 years of housing in 15 minutes. That matters when we're diagnosing a pet odor problem because the right treatment depends on what's under the carpet.
In the older parts of Aurora — McCarty Burlington, the Near Eastside Historical District, downtown side streets — the homes are from the 1900s and 1910s. Original hardwood under decades of carpet, lath-and-plaster walls, narrow lots. Pet accidents in these homes have usually soaked through into the original floor. The good news is that pine and oak subfloors are easier to seal than concrete; the bad news is that previous owners' cats from the 1980s might still be smelling up the master bedroom.
Out in Far East Aurora — Wheatlands, Blackberry Trail, Kensington Lakes, the Naperville-adjacent subdivisions — it's a different world. These are 2000s and 2010s builds with finished basements, three-car garages, and open-concept first floors. The carpet pad is younger but the volume of traffic and accidents is higher because the houses are bigger and the families have more pets. We see more multi-cat households on the east side and more big-dog accidents in the great rooms.
Our process handles both. UV inspection, severity assessment, deep treatment of the actual contamination layer (whether that's pad, plywood, or concrete), dwell time, and full sub-surface extraction. Aurora is about 38 minutes south of our Algonquin headquarters via IL-31 and US-30, and we run that corridor several times a week.
You've scrubbed the spot, tried enzyme sprays from the pet store, maybe even hired a carpet cleaner. It smells fine for a few days — then on the next humid afternoon or when the heat kicks on, the odor is back. You're not doing anything wrong. The problem is that pet urine doesn't stay where you can reach it.
When a dog or cat urinates on carpet, gravity pulls the liquid down through the fibers, through the carpet backing, and into the pad. In repeated or severe cases, it reaches the subfloor. As the moisture evaporates, what's left behind are uric acid crystals — microscopic, odor-producing compounds that are invisible, nearly indestructible, and completely unaffected by standard carpet cleaning.
Pet urine spreads wider and deeper than the visible stain on the surface. Store products and standard carpet cleaning can't reach the crystals trapped in the pad and subfloor.
Enzyme cleaners from the pet store only penetrate the top carpet fibers. They can't reach the pad or subfloor where most of the urine has settled. You're treating 20% of the problem.
Standard carpet cleaning uses deodorizers that mask the smell with fragrance. The uric acid crystals are still there. When the perfume fades, the urine odor returns — often stronger.
A dog or cat's nose is 10,000 to 100,000 times more sensitive than yours. Even when you can't smell anything, your pet can — and will return to the same spot until the uric acid is completely eliminated.
This is why we built a process specifically designed to reach every layer — fiber, backing, pad, and subfloor — and destroy the uric acid crystals at the source. It's the only way to guarantee the odor is truly gone. See our 7-step process →
Same 7-step process for every job, refined over 40+ years. Here's the short version — for the deep-dive on each step, see the main process page.
Our Aurora-area technician arrives in about 38 minutes from our Algonquin headquarters and maps every contaminated spot before quoting.
We tell you honestly which spots are treatable and which need replacement.
We apply our urine-targeted solution directly to the affected pad and subfloor.
The chemistry breaks down uric acid crystals over a controlled wait period.
We pull contaminated solution out of the pad — not just the surface.
The carpet fibers get a complete clean as the final pass.
If you can still smell urine after the carpet dries, we come back at no charge.
We don't use stock photos or made-up stories. These are actual pet urine removal jobs from Aurora homes — with real before-and-after results.
A homeowner in the Near Eastside Historical District called about a smell in the master bedroom that had been there for years. UV inspection through the carpet showed contamination that had soaked into the original pine subfloor — likely from cats owned by a previous family in the 1980s or '90s. We treated the carpet, then pulled the corner back to seal the wood directly. Single visit, smell gone for good.
A Wheatlands family with two large Golden Retrievers had been masking a great-room odor with plug-ins for over a year. Our blacklight found five overlapping spots near the back patio door. Treatment, dwell time, and full truck-mounted extraction in one visit. The owner reports the room smells like a normal living room for the first time since they moved in.
A Kensington Lakes home with three indoor cats had developed a strong basement smell that the homeowner couldn't trace. UV mapping showed eight deposit zones across the basement family room. We treated the pad, dwelled, extracted, and walked the homeowner through what we found. Two-week follow-up confirmed total elimination.
Most carpet cleaners offer pet urine treatment as an add-on. We built our entire process around it. Here's what separates AOK from every other option in Kane County.
No other carpet cleaner in the area makes this promise. Most use hedge language like "reduces odors" or "up to 90% removal." We guarantee the odor is completely gone once the carpet dries — or we come back and retreat at no charge. If we can't fix it, you don't pay.
AOK has been cleaning carpets in Northern Illinois since 1981. We've handled thousands of pet urine situations — from a single puppy accident to multi-year cat urine saturation through the subfloor. There isn't a scenario we haven't seen.
If your carpet can be saved, we'll save it. If it can't — if the urine has saturated the subfloor beyond what treatment can reverse — we'll tell you to replace the carpet instead of charging you for work that won't hold.
Our truck-mounted system generates significantly more suction and heat than the portable units most competitors use. That extra power is what allows us to extract dissolved urine from deep in the pad.
Our treatment solutions are non-toxic and safe for children and animals once dry. No harsh chemical fumes, no residue left behind. Your pets can be back on the carpet the same day.

Both dog and cat urine cause persistent odor problems, but for different reasons. Here's how we handle each.
Dog urine tends to spread across larger areas and soaks down quickly into the pad. The volume per accident is bigger, but the urine is generally less concentrated than cat urine.
Treatment usually focuses on a few specific zones — often near doorways, water bowls, or favorite resting spots.
Cat urine is more concentrated and harder on carpet fibers. The crystals lock in tighter and reactivate with humidity.
Repeat offenders almost always require treatment of the pad and sometimes the subfloor. Full breakdown on our main page →
“We have a historic home on the east side and a smell in the master bedroom that I thought was just "old house." AOK proved it was previous-owner cat urine and got it out completely. I'm a believer.”
“Two big dogs, big great room, big problem. AOK fixed it in one visit. The technician was honest about what was treatable and what wasn't, and the result speaks for itself.”
“Three cats and a finished basement is a tough combination. AOK handled it without any drama. The basement is usable again and the smell is completely gone.”

Cost depends on the number of affected spots, how deeply the urine has penetrated, and total square footage. Every job starts with a free UV inspection so we can give you an accurate quote based on what we actually find.
In most cases, yes. Our treatment is designed to save the carpet by neutralizing urine deep in the pad. In severe cases where the urine has soaked into the subfloor, replacement may be the better call — we'll tell you honestly which it is.
No. When the uric acid crystals are fully neutralized and extracted, the odor does not return. If you can still smell urine after the carpet has fully dried (24–36 hours), we come back and retreat at no charge — that's the guarantee.
Most jobs are completed in a single visit. A typical 2–3 room job takes about 2–3 hours including inspection, treatment, dwell time, and extraction. Carpets are walkable in hours, not days.
Yes. Our solutions are non-toxic and safe for children and animals once dry. There are no harsh chemical fumes during or after the process.
Yes — we serve all of Aurora, from the historic Near Eastside and downtown out through the Wheatlands, Blackberry Trail, and Kensington Lakes subdivisions on the far east side. We're about 38 minutes south of Aurora via IL-31 and US-30 from our Algonquin headquarters, and Aurora is one of the corridors we run several times a week.
We're about 38 minutes from Aurora via IL-31 south to US-30 / I-88. Same-week appointments most weeks. Every job is backed by our 100% odor removal guarantee — if you can still smell it, you don't pay.
